Where these figures come from. Nutrition figures come from In-N-Out's official Nutrition Info page (in-n-out.com/menu/nutrition-info), read in full on 28 Oct 2026 and re-confirmed from the official nutrition PDF's text layer (chart revision January 2026, printed "©2026 In-N-Out Burgers"). The official page publishes per-item panels — one burger, one order of fries, one shake, one drink at a stated size — and this section follows that serving basis exactly. Drink rows are at the smallest listed size with ice (11 fl oz for fountain drinks and lemonades, 6 fl oz for teas); the larger sizes are shown alongside. Where In-N-Out has no panel, the item is shown without one — never estimated.
